mex鏈接器找不到mex功能符號

Question

直到最近我已經能夠在我的mac osx 10.8.4 上編譯mex函數，但現在它給了我如下錯誤（爲了方便起見，我已經包括了整個-v調用）：

我已經將原始的mexopts.sh文件複製到本地目錄，以確保mex編譯器使用正確的版本。我以前也使用g ++編譯過我的cpp文件，只是爲了確保代碼是爲x86_64架構本身編譯的。但是，當我嘗試使用mex編譯器進行編譯和鏈接時，會出現相同的結果。 關於這裏可能會發生什麼的任何想法？似乎人們之前有過這個問題，但主要是缺少圖書館或定義。我已經在我的源文件中明確定義了一個mexFunction。

我認爲荷銀是正確的，我會把這個作爲一個評論，但它是一個有點大，我覺得這是爲clang command line options to select target CPU

Registered Targets: 
alpha - Alpha [experimental] 
arm  - ARM 
bfin  - Analog Devices Blackfin [experimental] 
c  - C backend ... ... 
mblaze - MBlaze 
mips  - Mips ...

x86  - 32-bit X86: Pentium-Pro and above 
x86-64 - 64-bit X86: EM64T and AMD64 
xcore - XCoreI'm thinking Amro is correct: 

所以是-arch x86-64正確的命令行開關，而比x86_64
